The rise in the fuel consumption has not only increased the demand for fuel, it has also increased the damage to the environment. All car companies are researching on different kinds of alternate fuels which will be harmless to the environment. The electric cars are not so efficient in performance to the normal gasoline cars and so it has not become popular. In the meantime, car manufacturers have started introducing hybrid vehicles. They are the normal cars which run on gas with an additional electric motor. The electric motor is used in slow speeds and this helps to save fuel.
Toyota Prius is the first mass produced hybrid vehicle. It is a mid sized hybrid electric car released worldwide in 2001. It is being sold in more than 40 countries now also making it the highest sold hybrid car till date. It is one of the most fuel efficient cars sold presently. It is also among the most cleanest vehicles in trems of carbon dioxide emission levels. The Prius has a special powertrain that combines a gasoline-fueled IC engine with an electric motor. This powertrain coupled with other features allows the Prius to deliver better mileage and lower emissions compared to regular cars.
